# DMA-BUF Configuration Validation Test
2+
3+
## Overview
4+
5+
This test validates the DMA-BUF subsystem configuration on Qualcomm platforms, including kernel configuration, device tree setup, and system interfaces.
6+
7+
## Test Coverage
8+
9+
### 1. Kernel Configuration Validation
10+
**Mandatory**:
11+
- `CONFIG_DMA_SHARED_BUFFER CONFIG_DMABUF_HEAPS CONFIG_DMABUF_HEAPS_SYSTEM` - Core DMA-BUF support
12+
13+
**Optional but Recommended**:
14+
- `CONFIG_DMA_HEAP` - Modern DMA heap interface
15+
- `CONFIG_DMA_CMA` - Contiguous Memory Allocator
16+
- `CONFIG_TEE_DMABUF_HEAPS`
17+
- `CONFIG_HAS_DMA`
18+
19+
### 2. Device Tree Validation
20+
- Reserved memory nodes (`/proc/device-tree/reserved-memory`) - informational
21+
- Platform-specific DMA heap nodes
22+
- Memory region sizes and configurations
23+
24+
## Usage
25+
26+
### Run directly:
27+
```bash
28+
cd /path/to/Runner/suites/Kernel/Baseport/dmabuf
29+
./run.sh
30+
```
31+
32+
### Run via test runner:
33+
```bash
34+
cd /path/to/Runner
35+
./run-test.sh dmabuf
36+
```
37+
38+
## Test Results
39+
40+
Generates:
41+
- `dmabuf.res` - Final result (PASS/FAIL)
42+
- Console output with detailed validation steps
43+
44+
## Prerequisites
45+
46+
### Required:
47+
- `CONFIG_DMA_SHARED_BUFFER=y` in kernel config
48+
49+
50+
## Expected Output
51+
52+
```
